Hex to Binary Converter

Convert hexadecimal to binary and back. See decimal values, bit counts, and formatted output. Useful for programming, debugging, and electronics work.

0-9, A-F

Quick examples:

Binary result will appear here

How it works: Each hexadecimal digit (0-F) represents exactly 4 binary digits (bits).

Example: Hex F = Binary 1111, Hex A = Binary 1010

How It Works

  1. 1

    Enter Hex or Binary

    Type a hexadecimal number (0-9, A-F) or binary number (0-1) in the input field. Conversion happens as you type.

  2. 2

    See Binary Output

    The tool converts each hex digit to its 4-bit binary equivalent using a lookup table. Results appear immediately.

  3. 3

    View Results

    See the converted value with formatted output, decimal representation, and bit count.

  4. 4

    Copy and Go

    Click the copy button to copy the result to your clipboard. Switch modes anytime to convert in the opposite direction.

Use Cases

  • Memory Address Translation

    Convert hexadecimal memory addresses to binary format for low-level programming, debugging, and understanding memory allocation patterns.

  • Digital Circuit Design

    Transform hex values to binary for logic gate design, FPGA programming, and digital electronics simulation work.

  • Network Configuration

    Convert MAC addresses and IPv6 notation from hex to binary for subnet calculations and network troubleshooting.

  • Error Code Analysis

    Decode hexadecimal error codes into binary to identify specific bit flags and understand system error states.

  • Character Encoding

    Convert Unicode code points and ASCII hex values to binary for text processing and encoding analysis.

  • Embedded Systems

    Work with register configurations, sensor data, and hardware interfaces that use hexadecimal representations.

Frequently Asked Questions

Hexadecimal uses 16 symbols: 0-9 and A-F. It's common in programming because each hex digit equals exactly 4 binary bits. This makes it compact - one byte (8 bits) = two hex digits.
To convert hex to binary manually, replace each hexadecimal digit with its 4-bit binary equivalent. For example: hex '3A' becomes '0011 1010' (3=0011, A=1010). Then remove leading zeros if needed. Our tool automates this process instantly.
Yes! The converter automatically handles the '0x' prefix commonly used in programming languages. You can enter values like '0xFF' or just 'FF' - both work perfectly.
Binary (base-2) uses only 0 and 1, representing the on/off states of computer circuits. Hexadecimal (base-16) uses 0-9 and A-F, providing a more compact notation. One hex digit equals exactly 4 binary digits. For instance, hex 'F' equals binary '1111'.
Programmers use hex because it's more readable than long binary strings while maintaining a direct relationship with binary. It's perfect for representing memory addresses, color codes (RGB), byte values, and bit patterns. Two hex digits represent exactly one byte.
Yes, the tool can convert hex numbers of any practical length. The conversion is performed digit-by-digit, so even very large hexadecimal values are converted accurately and instantly.
Absolutely! You can convert hex to binary or binary to hex. Just click the swap button or select the desired conversion mode. The tool validates input for both directions and provides formatted output.
The formatted output adds spaces for readability. Binary values are grouped in 4-bit nibbles (matching hex digits), and hex values are grouped in pairs (matching bytes). This makes it easier to read and verify long numbers.
Yes! Hex color codes (like #FF0000 for red) can be converted to binary. Remove the # symbol and convert each pair of hex digits. This is useful for understanding how colors are stored and manipulated in computer graphics.
Yes. Everything runs in your browser - no data leaves your device. Works offline too.
